Charles Emmanuel Reinhardt (1868–1920) was a British physician, animal welfare activist and anti-vivisectionist.
[1] He established the Hailey Open-Air Sanatorium at Ipsden, Wallingford and acted as visiting physician.
[4][5][6] In his book Diet and the Maximum Duration of Life, Reinhardt argued that colon cleansing was responsible for postponing old age.
[7][8] Reinhardt was influenced by the research of Élie Metchnikoff and was one of the earliest physicians to promote the consumption of yoghurt.
In 1912, Reinhardt attended a meeting at Torre Abbey in which he defended animals as akin to humans because they feel pain and experience suffering.
